I have a server room which is being ventilated by two cylindrical plenums with holes 1 inch OC supplying air and a single exhaust vent on the top.

 

I have successfully ran the model and am setting up the results. It seems like no matter how many streamlines I add I cannot get streamlines to show the air coming out of the last two or three holes. I know that the mesh is good on those holes and that air is coming out.

 

I have added 4 images. Three are images of the streamlines at each view. I have circled the holes in which air does not seem to be flowing out of.

 

However, the fourth image is a contour plot down the middle of the holes and shows that equal amount of air are coming out of each hole at around the same velocities (5 m/s).

 

Does anybody have any idea why I cant get streamlines to reflect what the contour plot says is happening?

 

Thanks

Hi seffa

Can you share this model with us for further investigation. I can send you a securetransfer link separately over email if the model is bulky or cant be shared on public forum.

Gaurav_ANSYS I did want to say that in those picture the seed location is set at the very begging of the air plenum. However, if I set the seed locations at the individual air holes then they do appear to show proper airflow. I think I will just add seed locations to all of them to ensure I get what I want.

Hope you encountered no further issue after doing the needful.

This was more of a graphical issue. If seed locations are set at each air hole then proper airflow is shown,
